prolly dynamic advance. on STi's i think it runs from .1 to 1 or something like that. this is the dynamic part of the ECM's iginition timing, and will lower itself when it thinks knock is present. low = knock, high = no knock.

oh i change my answer... if the range is like you said mark, it's prolly not the DAM (like i thought), it is indeed the actual amount of timing added to the base map. which the DAM is used to calculate.

there is dynamic advance (the amount of timing addded).

and dynamic advance multiplier (the number that varies to dictate the actual amout of timing to be added)

wgduty i'm guessing is the percentage the wastegate opens to prevent overboost? the highest i can make it go is when it's in 5th and i step on the pedal at about 3k rpms, it goes to 78. the MAF is a weird number too... it hangs out arouns 2-4 at idle but at wide open throttle in say 3rd gear i had it over 200. i know it's not voltage now IGN doesnt do much either... i'll have to list all the other live readings and post them, and if you want me to test something and post it lemme know.

This adjustment is made to the Dynamic Advance value and can be seen in a datalog. If your DA value for a particular load point is 8 and your DAM is showing as .50, then you should log a 4 as your DA value. If you do not see 4 in the logged value for DA, this means the Knock Learning table has been populated with a value or your ECU made a final adjustment to ignition advance because the ignition advance for that particular condition (RPM & Calculated Load) is too close to threshold.

+/- adjustment make by ECU within Knock Detection range. Within the Knock Detection range, the ECU can
make a final adjustment to remove ignition advance is it hears the engine noise is getting too close threshold.

Make sense?

There are definitions before this, but what you see above is how they work together.

right... i'm DBW and i'im reading 7.5 Not correct, this stuff makes no sense, no answer on cobbforums either. So pretty much everyone with a v2 Ap is clueless.

Dynamic Advance of 7.5deg is not impossible.
edit-> It doesn't mean much w/o DAM, RPM, load, and ignition table settings. More ignition tables than you'd think.

It doesn't make sense to you, but the data may not be useless to your tuner. You may be missing too much information to make sense of it. It may not seem intuitive, but I've found the system to be flexible and (most importantly) safe.

yesssssssss i read it. still, the most info i've gotten is from a street tuner PDF to a forrester. Cobb needs to put out a supplement that says Ign = this, dyn adv = this, WG duty measures this... It's like getting features on a cell phone and they don't define them in the manual.

without knowing what the dynamic advance values are for a specific RPM and load site, the dynamic advance number that spits out of your AP is useless. and the MAF reading, is Grams/Sec of airflow. 1 Gram/Sec = ~ 1 WHP, If everything else is optimized (fuel, spark etc.)
